Abstract
A single chip, base-band to RF, BiCMOS transmitter RFIC (RFT3100) for dual-band CDMA/AMPS wireless handsets is presented. The RFIC contains base-band I/Q modulator, UHF VCO buffer, IF PLL, VCO, IF and RF VGAs, image rejection RF upconverter, dual driver amplifiers for cellular and PCS bands, and a three wire serial interface to control the chip. The chip operates from a 2.7 to 3.3 V supply, a temperature range of -30 to 85/spl deg/C, and is packaged in a 32 lead 5/spl times/5 mm bump chip carrier (BCC) package. The chip is fabricated using a 18 GHz (analog NPN ft), 0.5 um BiCMOS process.Keywords
